Analytical Applications unit test
A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

9 ptsLet f(x) = x³ − 6x² + 9x + 2.
Find all critical points of f and classify each as a local maximum or local minimum. Justify your answer.
Find the inflection point of f and the interval on which f is concave up.
Find the absolute maximum and absolute minimum values of f on the closed interval [0, 4].
